Thread: So I'm oficially in desperate need of some suspension advice.

Tampa, FL area, a little south of that.

BTW, thanks for all the suggestions, I'll try to check everything I can out, starting with the corners.

I haven't adjusted the rear bar any. It's at full stiff, basically.

1. Corner Weight before you do anything! Everything regarding weight and placement are simply theories until it is weighed.

Things that can improve on the above being adjusted properly.

2. Rear beam bend and super pro bushings, front caster bushings, progress adjustable front bar.

It won't get you the correct weight of your vehicle, but if you have the same size/model tires all around it can get you the corner weight ratios:

Can You Weight A Car ?!?! - Video

Do it on a level surface with the same pressure in each tire to make it easier and remove some variables.

Get back to us. =]

I have to ask...was your name Reverm on NissanForums?

Thank you for that video, LOL, I wish I thought of that little technique. Anyhow, as inaccurate as it may be here are my numbers (keep in mind, I have 225w tires):

38.0PSI, fresh filled.
FL: 5-1/16 x 6-7/8" = 34.805in2 *38lb/in2 = 1322.59lb
FR: 5-1/16 x 6-5/8" = 33.539in2 *38lb/in2 = 1274.482lb
RL: 4-3/16 x 6" = 25.125in2 *38lb/in2 = 954.75lb
RR: 4-3/16 x 6" = 25.125in2 *38lb/in2 = 954.75lb

Obviously, my car doesn't weigh 4506.572lbs, but at least I have some ratios.For simplicity, I'm dividing all the weights by 2, because the car is closer to 1-ton, rather than 2 tons, so total weight, we'll assume 2253.286.

FL: 1322.59/2/2253.286= 29.34%
FR: 1274.482/2/2253.286= 28.28%
RL: 954.75/2/2253.286= 21.19%
RR: 954.75/2/2253.286= 21.19%

F/R: 57.62/42.38

For the record, my fender heights just happen to be 2' 1/4" all around from the ground to the highest point of the fender arch. This is as low as the car can go without my tires rubbing on bumps.


edit: more info, according to edmunds.com, the SE-L is 2617lbs from the factory (auto) and to whoever said I may have taken too much weight off the front wheels, you could be right. I don't know the exact numbers for my car, but I see most FWD cars are about 62/38.

.....dbl post.

Yep. Why do you ask? ; )

I know it's a bit of a ways off, but there's a place called Irish Mike's in Orlando that does race prep. Here's the URL:

Irish Mike's Racing

No affiliation.

EDIT:

I wouldn't take those numbers to heart just yet. There are a lot of factors that can throw off the results of that grassroots corner weighting method. Just to name a few:

• Measuring on a working surface that isn't perfectly even and level
• Measuring a car with different camber settings front and rear
• Measuring a car with low profile radial tyres
  

So don't be too surprised if you see some very different results when you get your car on a set of digital scales.
